Instructions for use

Preparation cracks

surface cracks should not contain impurities (fat stains, dust, etc.).

clear surface area to sound concrete. If the crack of small volume, expand it to the width and depth (at least 20 mm) case. Before the injury solution produced damping surface water. Preparation of material

Using gloves, razmeshat small amount of low capacity, in a ratio of 220 grams of water per kilogram of dry mixture. The optimal water temperature +70 ° C.

duration of mixing should not exceed 2 minutes. Do not mix more than you can use for 3 minutes (no more than 500 grams).

Do not use grapple material repeatedly.

Processing cracks

Apply immediately after mixing. Make the material form a cylinder, vdavit it in a crack or cavity pressing strong hand in glove, a wooden wedge or other flat object. Held in place at least 1 hour. If water is leaking badly, to keep a cork for 6 minutes using vodopogloschayuschih materials. The excess material is removed with a knife or other sharp object.

Long, tekuchie, vertical cracks stop a top-down, consistently causing small amounts of water plugs.
